COMBINED POCKET-KNIFE AND PHYSICIANS SCALE.

SPECIFICATION forming part of Letters Patent No. 460,147, datedSeptember 29, 1891.

Application filed March 14, 1891.

To all whom it may concern.-

Be it known that I, EDWARD D. MILES, a citizen of the United States ofAmerica, residing at Iconium, in the county of St. Clair and State ofMissouri, have invented certain new and usefullmprovements in a CombinedPocket-Knife and Physicians Scales, of which the following is aspecification, reference being had therein to the accompanying draw-1ngs.

This invention relates to a combined pocket-knife and physicians scales,having for its object the production of cheap and simple means whereby aphysicians scales can be conveniently attached to a pocket-knife readyfor use, and at the same time not materially add to the weight or bulkof the knife, and can be carried in the wearers pocket as an ordinaryknife.

The invention comprises a pocket-knife and a scale-beam detaehablysecured to one side thereof.

The invention further comprises a pocketknife, a scale-beam detachablysecured to one side thereof, a fulcrum or rest bar, and a scalepan, allof which are firmly secured to the knife when not in use.

The invention further comprises the detail construction, combination,and arrangement of parts, substantially as hereinafter fully set forth,and particularly pointed out in the claims.

In the accompanying drawii'lgs, Figure 1 is a view in side elevation,showing a pocketknifeconstructed in accordance with myinvention. Fig. 2is a similar view showing scale-beam in position ready for removal. Fig.3 is a view in perspective of the scale-beam as used in practice. Figs;4 and 5 are details, the former of the fulcrum-bar and the latter of thescale-pan. Fig. 6 is a bottom view of the fulcrum-point of thescale-beam.

Referring to the drawings, A designates a pocket-knife, the outercovering of one side of which is omitted. From the side a of this knifeprojects a headed lug or stud a, and near the reduced end of said sideis formed a transverse groove or recess a B is a scale-beam, whereon arescales or marks of graduation b. This beam consists of a long flat barhaving a widened portion Z),

Serial No. 385,095- (No model.)

wherein is formed an oblong slot b which corresponds with the lug 01'stud a when the bar is placed transversely across the knife. One side ofslot 11 is beveled or inclined, and in the widened portion 1) is atransverse groove 11 A sliding weight 0 is placed on the scale-beam, andthe same is designed to rest in groove or recess a when said beam issecured to a knife.

D is a fulcrum bar or rest for the scale-beam, and it consists of a bar(Z, having widened ends, and a cross-bar (1, of V shape in crosssection,provided with a central crest or point (1 designed to fit into slot bwhile the remaining portion its groove b of the scalebeam. In thismanner afulcrum is provided for the scale-beam. In one end of said beamis a hole or aperture (Z wherein is designed to fit a lug or stud d,projecting from the bottom of ascale-pan E, which latter is preferablysquare in shape.

From the foregoing description it will be seen that medicines and thelike can be readily and easily weighed, the poise being capable of beingmoved to any point to balance the scale-pan and its contents. The scalesare secured to the k nife-handle by first placing the scale-beam in theposition shown in Fig. 2, turning the same at right angles, so as toextend longitudinally the length of the knife, and the weight fits snugin the groove or recess formed therefor. The fulcrum -har is thenpressed down over the widened end of the knife, (a groove 10 beingpreferably formed in the side cover 10' for reception of one side or endof said fulcrum-ban) and the scale-pan is then forced down over thefulcrum-bar, holding the same and the scale-beam firmly in position onthe knife.

The advantages of my invention are obvious. The same is of greatconvenience to physicians practicing in small districts at distancesfrom druggists.

The invention is extremely simple, cheap, and durable, and a pocketknifethus constructed is not perceptibly increased either in weight or bulkand can be carried in the wearers pocket as an ordinary knife. Then,again, the physician or user has the further advantage of having at handa knife ready for use for cutting purposes or for placing powderedmedicines in the scale pan or spreading poultices and the like.

I claim as my invention- 1. The herein-described improved pocket knifeand scales combined, comprising the knife and the scale-beam detachablysecured to the side thereof, as set forth.

2. The herein-described improved pocketknife and scales combined,comprising the knife, the scale-beam detachably secured to one sidethereof, the fulcrum-bar having parallel sides or ends and designed tofit over one end of said knife and hold said scale-beam, and thescale-pan inclosing said fulcrum-bar and end of knife and scale-beam,substantially as set forth.

3. The herein-described improved pocketknife and scales combined,comprising the knife having a headed lug or stud and a groove or recess,the scale-beam havinga slot through which said ing or stud is designedto project, the sliding poise on said beam designed to enter said grooveor recess, the fulcrum-bar having parallel sides or ends and designed tofit over one end of said knife and hold said scale-beam, and thescale-pan inclosiug said fulcrum-bar and end of knife and scale-beam,substantially as set forth.

4. The combination of the scale-beam havinga widened portion,agroove orrecess, and a slot, the sliding poise on one end of said beam, thefulcrum bar or rest having an upper cross-bar entering said groove orrecess and slot, and the scale-pan secured to said beam, substantiallyas set forth.

5. The combination of the scale-beam having a widened portion, a slotformed therein and a hole in one end of said beam, the sliding poise,the fulcrum bar or rest having an upper crossbar V shape incross-section and provided with a central crest, and the scalepan havinga lug or stud projecting from its bottom and designed to fit in saidhole of the scale-beam, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
